12-card SLI configuration

Just got done installing my 12th Radeon 6900 in SLI configuration, as you can see from the image below:



Actually, I'm just tired of looking at this whenever I right click Catalyst. I have to assume something is not working properly, which is obviously unacceptable when you spend a lot of money on your system. In actuality, I only have two 6900's running Crossfire on an EVGA P67 FTW with latest bios. Naturally, first thing I did was completely wipe drivers and reinstall to no avail. I would be much obliged if someone can suggest a starting place to clean this mess up. I will be happy to provide whatever additional data would be diagnostically useful. Thanks in advance for your help.
